Here are links to the suppliers that I've been checking out:

• Gurney's Seed and Nursery (planning to order here; there's a buy-$25-get-$25-free discount until March 18) 
• The Cook's Garden (planning to order some veggie and herb seeds from here; there's a $5-off-$30 discount until June 30)
• Gardener's Supply Company (planning to order some supplies from here)
  
• One Green World (planning to order fruit plants from here; based in Oregon)
• Territorial Seed Company (I've used their seed in the past; based in Oregon)
  
• Park Seed (10% discount, plus a discount seed section)
• Breck's (bulbs)

Also for DIY inspiration, be sure to check out The Cheap Vegetable Gardener (especially the Cheap LED Grow Box).

Based on Teena's post, I'm planning to switch my seed order to Seed Savers Exchange.

I'm now planning to order from:

• Seed Savers Exchange (non-profit heirloom seed exchange - vegetables and herbs)
• One Green World (local to Oregon - fruit)
• Freshops (local to Oregon - hops)
